Tyk vs. Kong

Tyk handles approximately 6,900 requests per second with 8.6ms p95 latency. Its Go-based architecture is memory-efficient and simple to deploy, but the Redis dependency for rate limiting and session management introduces additional latency. For high-throughput environments, Tyk often requires more gateway instances than NGINX-based alternatives.

Kong achieves approximately 16,000 RPS per node — more than double Tyk's throughput. Its NGINX foundation handles concurrent connections efficiently through an event-driven model. PostgreSQL/Cassandra configuration storage adds operational complexity but doesn't significantly impact per-request latency.

Apache APISIX reaches 23,000 QPS per core with 0.2ms average latency — approximately 3x Tyk's throughput and 1.5x Kong's. In published benchmarks, APISIX consistently delivers the highest throughput among open-source API gateways. When plugins are enabled, APISIX outperforms Kong by approximately 200%, as plugin execution in LuaJIT is significantly faster than Kong's Lua-based approach.

Tyk's strongest differentiator is its built-in Developer Portal, available even in lower-tier plans. It provides customizable branding, self-service API subscription, API analytics, and monetization capabilities out of the box. For teams that need a complete API management experience without paying Enterprise prices, Tyk delivers more value than Kong's open-source edition.

Kong's Developer Portal is Enterprise-only, starting at approximately $50K/year. Teams on the open-source tier must build their own developer onboarding workflows. Kong Konnect adds cloud management and analytics at additional cost. This feature-gating pushes most production teams toward the paid tier.

API7 Enterprise includes the API7 Portal with documentation, developer onboarding, monetization, and self-service subscription. Combined with 100+ open-source plugins, canary releases, traffic splitting, and request transformation, API7 delivers full lifecycle management at a fraction of both Tyk and Kong Enterprise pricing.

Tyk supports custom plugins in Go, Python, JavaScript, and via gRPC protocol. Its plugin ecosystem is smaller than Kong's but covers the most common API gateway patterns. Tyk does not support plugin hot reload — configuration changes require gateway restart or reload cycle, introducing brief downtime.

Kong has the largest plugin ecosystem (100+ plugins) but locks many production-critical features behind Enterprise: OIDC, OPA integration, advanced rate limiting, and mTLS. Custom plugins can be written in Lua, Go, or JavaScript. Like Tyk, Kong does not support true plugin hot reload.

Apache APISIX provides 100+ plugins — all fully open-source with no enterprise paywall. Custom plugins support the broadest language range: Lua, Go, Wasm, Python, JavaScript, and Java. Critically, APISIX supports true plugin hot reload — plugins can be updated without restarting the gateway, enabling zero-downtime configuration changes in production.

Tyk scales by adding gateway instances connected to shared Redis and MongoDB/PostgreSQL. This works well for moderate deployments but introduces database infrastructure as a potential bottleneck. Redis dependency for rate limiting and session management means Redis availability directly impacts gateway functionality.

Kong scales by adding nodes to a PostgreSQL or Cassandra cluster. Configuration synchronization uses database polling with 5-10 second propagation delay. If the database fails, the gateway continues serving cached configuration but cannot accept new changes. Database expertise is required for production scaling.

Apache APISIX uses etcd for configuration storage — a lightweight distributed key-value store designed for exactly this use case. Configuration changes propagate in milliseconds through etcd watch. Each APISIX node is stateless, and both APISIX and etcd support multi-instance deployment with no single point of failure. This architecture is fundamentally more resilient than the relational-database-backed approaches of both Tyk and Kong.

Tyk uses the Mozilla Public License (MPL 2.0), which is more restrictive than Apache 2.0. The project is primarily developed by Tyk Technologies, and its smaller open-source community means fewer independent contributions and longer resolution times for community support. Enterprise features are proprietary.

Kong's open-source core is Apache 2.0, but Enterprise features are proprietary. Kong Inc. controls the project roadmap, and community discussions about licensing changes have raised concerns. Organizations building around Enterprise features face meaningful migration costs if they need to switch.

Apache APISIX is governed by the Apache Software Foundation under the Apache 2.0 license. No single vendor controls the project. The community has grown rapidly — with more active contributors than Kong — ensuring continuous development independent of any company. API7 Enterprise builds on this open foundation with commercial support, management console, and SLA guarantees without adding proprietary lock-in.
